Location-Aware Mobile Object Control for Road-Sidewalk Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to appropriately control mobile objects transitioning from roadways to predetermined regions like sidewalks, leading to potential control issues and safety hazards.
Innovation Solution
A mobile object control device and method that includes a hardware processor to recognize the object's behavior, detect contact points between roadways and sidewalks, and adjust speed accordingly, limiting speeds on roadways and sidewalks differently to ensure safe transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile object maintains a constant high speed on the roadway, then productivity is improved, but safety deteriorates when transitioning to the predetermined region
Solution Approach 1:
The control device dynamically adjusts the speed limit based on the mobile object's location. When on the roadway, the object can travel at higher speeds for productivity. When approaching or on the predetermined region (sidewalk), the speed automatically reduces to ensure safety during transition
Solution Approach 2:
The control device performs preliminary speed reduction before the mobile object actually enters the predetermined region. By detecting the approach to the sidewalk and reducing speed in advance, the system prevents sudden deceleration and ensures safe transition
2Reliability
If the mobile object reduces speed before entering the predetermined region, then safety is improved, but productivity deteriorates due to slower movement
Solution Approach 1:
The system dynamically adjusts speed based on location context. High speed is maintained on the roadway for productivity, while speed reduction is applied only when approaching or entering the predetermined region for safety
Solution Approach 2:
Different speed requirements are applied to different spatial zones. The roadway allows high speed operation, while the predetermined region and its approach zone require reduced speed, creating location-specific speed control
3Adaptability or versatility
If the mobile object frequently changes direction or speed, then adaptability to the environment is improved, but stability deteriorates due to unsteady behavior
Solution Approach 1:
The control device performs preliminary speed reduction when approaching the contact portion between roadway and predetermined region. This gradual adjustment prevents sudden directional changes or abrupt stopping, maintaining behavioral stability while adapting to the environment

AI summary
A hardware processor of a mobile object executes a program stored in a storage device to acquire information indicating a behavior of a mobile object; to recognize whether the mobile object is moving on a roadway or a predetermined region; to recognize presence of a contact portion between the predetermined region and the roadway; to limit a speed at which the mobile object is moving on the roadway to a first speed; to limit a speed at which the mobile object is moving on the predetermined region to a second speed slower than the first speed; and to bring a speed of the mobile object closer to the second speed when the mobile object is moving on the roadway, the contact portion is recognized within a predetermined range from the mobile object, and a behavior of the mobile object satisfies a predetermined condition.
